CADCAM options for the open-minded

 

Design options are best visualized and Vestdavit’s 2D and 3D davit digital library of drawings is putting CAD files where they belong – at the disposal of ship designers for download to include at the concept stage. By being available to ‘cut and paste’ images into main vessel design drawings, those specifying or recommending davits can easily envisage the implications of the different models available.

Vestdavit’s large range of davits, covering naval, coastguard, commercial marine and offshore sectors, can be accessed via a web portal developed with CAD-based platform innovator SolidComponents. Drawings are available as Step files in all relevant CAD formats and the files are easy to work with and download for use within overall vessel design, and continuously updated.

A downloaded davit drawing, including accurate measurements, can simply be pasted into the project a designer is working on. Designers can also explore a menu of optional Davit extras to refine their specifications.

“Naval architects log into the Vestdavit digital library and can download exactly what they need within a couple of minutes, without the frustrations of exchanging large data files via email or follow up phone calls,” says Bjørnar Dahle, Vestdavit Sales and Business Development Director. “Using the digital database means that naval architects can have the exact drawings they need at their fingertips. Envisaging the way adjusting one parameter affects other parts of the davit installation is an automated process, meaning that designers can see the consequences of their decisions in an easily navigable procedure.”

Five-year service for PAPH-10000

The revolutionary SWATH Wandelaar, designed and built by Abeking & Rasmussen for the Belgian Pilots, is a special vessel for Vestdavit, featuring two of our ground-breaking PAPH-10000 davits. The vessel, operated by Flemish Government subsidiary Vloot, has just completed its first five-year inspection and maintenance overhaul in a 12-day drydocking followed by sea trials in Dunkirk.

Lead Vloot superintendent Benoît Versavel took time out to praise the service offered by our engineers as part of the load tests, safety tests and general overhaul of the PAPH-10000 davits he describes as “reliable workhorses”. “Overall I am really pleased,” he says. “The technicians are friendly, but very professional and perform excellent work.”

The PAPH-10000 provides something of a model for product development here at Vestdavit, which is perhaps why servicing units in service brings the best out of our service technicians. Its conception can be traced to a single phone call from A&R. “We have a client with a special need,” we were told.

The ‘client’ turned out to be the organization representing the pilots who operate along the Elbe, whose high expectations stretched our best designers and Naval Architect, while also requiring willingness to engage fully with A&R project management, pilot management and crew.

The result was, and still is, the most advanced davit we have ever made – the PAPH type, single point davit for MOB and FRDCs, characterized by its compact design and its Anti-Pendulation Device. The PAPH-10000 is PLC computer controlled with preprogrammed sequences for launching and recovering the boat.  This enables the capability for multiple embarkation positions. The two davits on board Wandelaar are used for as many as 7,000 operations yearly, transferring pilots to and from ships outside the port of Antwerp. The vessel plays a key role keeping ship traffic running in this busy port.

Expedition ships to get Mission Ease

Vestdavit has turned its attention to the way its MissionEase multiple-boat handling system for hangars and mission bays can make boat handling on passenger ships safer and simpler as a new generation of expedition yachts and ice-strengthened cruise ships seek the spectacular destinations found in harsher locations.

First delivered to an offshore customer at the end of 2016, MissionEase is equally at home in the luxury passenger vessel setting, where it can stow, launch and retrieve up to 24 ribs (typically of 7-8m in length), kayaks, waterjets and similar equipment.

MissionEase is simpler, quicker, safer and cheaper than any other boat handling system for mission bays available. It brings together Vestdavit’s experience in naval and seismic ships to make the best use of any hangar or mission bay with a deck-height of up to 2,900mm.

Rather than using overhead cranes within the mission bay, MissionEase works on a system of hydraulic cradles which move boats safely from their stowage positions to maintenance, preparation or launch areas. It links seamlessly with single-point davits to deploy or recover boats from both or one side of the vessel, enabling one operator using a remote control to launch and recover the mission boat, including all on-deck handling.

“The ability to deploy and recover boats safely is part of the main armory of today’s expedition cruise ships and yachts,” says Rolf Andreas Wigand, Managing director, Vestdavit. “A mission bay allows the boats and other equipment to be stored, maintained, prepared and launched from a safe environment with a dry, freeboard. But the way existing systems rely on overhead gantries to move the boats within the bay can be dangerous, while slinging and unslinging can take time.

“MissionEase allows boats to be moved safely and quickly on cradles, even in high seas or during a vessel listing. The boats and other equipment are fed directly to the davits for launch, or feed directly back into the stow when recovered.”

PAP-16000 is the new lifting force

Vestdavit recently completed its largest ever single-point A-frame davit for over-the-side boat handling, as we continue to rise to challenges set by our customers for the launch and retrieval of ever-larger workboats from their ships.

The first PAP-16000 davit, which features a safe working load of 16t, will be installed on board a service operation vessel destined for a specialized segment in the offshore industry for an unspecified owner. The 58.5 m length vessel, due delivery by the end of 2017, will operate off north continental Europe.

The PAP-16000 has received approval from DNV GL and can handle workboats in conditions of up to sea state 5. It features an anti-pendulation docking head and guiding arms to limit load sway in adverse weather.

We have supplied bigger davits. We have delivered dual-point/winch davits of up to 36t SWL a 30t single point davit for stern operations, making us the market leader in handling very large workboats. However, the PAP-16000 is our largest single point davit with docking system for lifting over-the-side of a ship to date, where single point handling of larger and larger workboats without compromising stability presents challenges.

The first PAP-16000 will need to lift one crew boat able to carry up to five personnel, but another able to carry a complement of up to 10 persons plus one ton of cargo. This means it needs to be flexible, while this first unit will also be distinguished by its high operating speeds, with the customer requesting lifting speeds of 45 m/min.

The PAP-16000 offered is our newest innovative option for owners of not only SOVs, but emergency response and rescue vessels, pilot ships, standby vessels, multi-purpose offshore vessels and other types of construction vessel.

Extreme low weight aluminium

Latest feedback suggests that the weight advantages of aluminium davits, long-accepted by navies, coastguards and fast ferry operators. are convincing owners in new markets to look again at the structural alternative to steel.

The Australian Border Protection recently decided to equip two more Cape Class Patrol Boats with PLAR-6500 aluminium davits from Vestdavit, having already installed 16 units on their eight new patrol ships to lift 6,500 kg Rigid-Hull Inflatable Boats (RHIBs). The self-tensioned davits feature shock absorbers, guiding rails, wire haulers, and independent HPUs, safely launching and retrieving boats at up to 10 knots in the heavy seas that stretch from the tropics to the Antarctic.

The lighter weight option is also preferred for fast patrol boat applications by the Royal New Zealand Navy, the Danish Navy, the Swedish Navy, the US Coast Guard and others. Furthermore, security-conscious authorities operating fast response craft in the Middle East and South Asia are newly engaging with the benefits conferred by the aluminum davits in the 850-7,000 kg safe working load range offered by Vestdavit.

Every kilo saved in onboard equipment weight can enhance vessel stability and add payload. At 30% lighter than their steel-structured equivalents the aluminum davit brings a tangible stability gain for lighter duty vessels, while also minimizing corrosion and being non-magnetic. Operationally, lower vessel CoG translates into better maneuverability, lower fuel consumption, greater speed responsiveness and an expansion of the ship’s operational window.

The Vestdavit blog recently went live and we’re inviting your comments.

As always, our aim is to serve the buyers and users of our davits, and for our products and services to be under continuous improvement. Those efforts don’t take place in a vacuum; they need to be based on dialogue with our customers on the challenges they face and the solutions we can suggest. Often, the solution comes via better communication.

The Vestdavit blog is a platform for our experts to offer their insights into latest developments in the technology, safety and operating efficiency of davits from Vestdavit.  We hope that they are useful, informative and, perhaps, a little entertaining.

Vestdavit PAP-16000 brings new davit lifting force to market

Vestdavit has completed its largest ever single-point A-frame davit for over the side boat handling, rising to the continuing challenge set by customers to be able to launch and retrieve ever larger workboats from their ships.

The first PAP-16000 davit, which features a safe working load of 16t, will be installed on board a service operation vessel destined for a specialized segment in the offshore industry for an unspecified owner. The 58.5 m length vessel, due delivery by the end of 2017, will operate off north continental Europe.

The Norwegian boat-handling specialist said it had received approval from DNV-GL for the new PAP-16000, which can handle workboats in conditions of up to sea state 5. It features an anti-pendulation docking head and guiding arms to limit load sway in adverse weather.

“Vestdavit has supplied bigger davits, but the PAP-16000 is our largest single point davit with docking system for lifting over the side of a ship to date,” said Atle Kalve, Vestdavit Development Director. “We have delivered dual-point/winch davits of up to 36t SWL and a 30t single point davit for stern operations, making us the market leader in handling very large workboats. However, single point handling of larger and larger workboats over the side without compromising stability presents particular challenges.”

The first installation will be onboard a vessel designed for flexibility, needing to lift one crew boat able to carry up to five personnel, but another able to carry a complement of up to 10 persons plus one ton of cargo, Mr. Kalve added.

In its first delivery, the new davit will also be distinguished by its high operating speeds, with the customer requesting lifting speeds of 45 m/min, which Mr. Kalve said demanded a comparatively high oil flow to achieve max hoisting speed at SWL.

In addition to service operation vessels, the PAP-16000 offers a new and innovative option for owners of emergency response and rescue vessels, pilot ships, standby vessels, multi-purpose offshore vessels and other types of construction vessel.

Fire in Vestdavit offices – Possible disruption of service

Vestdavit and all staff would like to express sincere thanks for the inquiries and good wishes sent to us by our industry partners, following the fire which occurred in the stairwell of our Bergen headquarters building on April 19th.

The safety of our staff is paramount, and we are happy to report that no one was injured in the incident, which is not connected to Vestdavit and appears to have started outside the building’s main entrance.

Nevertheless, public spaces in the building have suffered smoke damage as a result of the fire, and the affected areas include part of our own offices. We have re-entered the premises and the clean-up operation is now fully under way.

The situation is firmly under control and Vestdavit will continue to operate as normally as possible. However, customers are kindly asked for their understanding over the coming days, in case our response times fall in any way short of the high standards we set ourselves as a company.

Vestdavit mission accomplished on Ramform safety

Seatrials are underway in Japan involving Ramform Hyperion, the last of four ships built to the seismic sector’s all-time highest specifications, completing a project that shows the way distinctive design also demands innovation from the equipment keeping ships safely in service.

Reckoned to be the widest monohulls at the waterline ever built, the Petroleum Geo-Services (PGS) vessels need a unique Vestdavit dual point boat handling solution to lift and lower tender boats in wave heights up to sea state 6. The boats work as Fast Rescue Craft with six crew, as tenders with 20 persons on board and as lifeboats with capacity for 40.

Ramform Hyperion, under delivery by Mitsubishi Heavy Industries, features a distinctive ‘5th generation’ hull form that is 104m in length and an extraordinary 70m across the beam, designed to deploy ultra-wide streamer tows aft. As a result, it has only a short, flat parallel ship side for tender boat launching and retrieval, necessitating a 12m outreach painter boom – the largest ever from Vestdavit or any other supplier.

“A standard davit solution was not compatible with the design of the ship itself; to work, it would be necessary for the vessel itself to be longer,” says Atle Kalve, Development Director, Vestdavit. “Involvement at an early stage of vessel design led us to a one-of-a-kind solution for workboat/lifeboat/FRC davit operations. From the outset, we also knew that davits used daily by ships expected to work two years at sea without interruption meant that no equipment downtime would be acceptable.”

Like its predecessors, Ramform Hyperion is fitted with two Vestdavit HN – 10000S dual point hydraulic davits, one on each side, with a dual winch system specifically developed for the application. Both the boom and the davits are computer-controlled and feature in-built auto tension and shock absorption optimising safety and crew comfort on launch and recovery in high seas. A 200 tonne Vestdavit shock absorber system takes peak loads out of the paravane doors during seismic operations to prevent the holding ropes from snapping.

“From the pure equipment point of view, we have delivered a motion compensating, multi-davit solution featuring dual winches, shock absorbers and synchronous lifting and lowering,” says Kalve. “From the user’s point of view, what sets the Vestdavit HN – 10000S solution apart is its self-levelling capability, without which it would not be possible to handle this extraordinary ship type’s boats in such high sea states.

“Our primary concern is always safety, but davits are also integral to everyday efficiency on these ships. We are handling expensive equipment and we need to eliminate shocks to make the process of deployment and recovery as smooth and efficient as possible.”
