Damen offshore series

Published in category: Offshore Wind

Damen is offering a fresh approach to offshore vessel customers. The company believes its global presence, combined with its continuing family-run ethos, can make a significant impression in a market characterised by niche yards. Damen has launched its extensive new Offshore Series, which is tailor-made for the industry.

This versatile new series includes five Platform Supply Vessel designs, ranging from 1,600 dwt to 5,000 dwt, Construction Support Vessels, the new Anchor Handling Tug & Supply (AHTS) Series ranging from 75 up to 240 tonnes, the Damen Offshore Carrier range and the Fast Crew Suppliers, as well as a variety of Offshore Pontoons. Designed especially for the offshore industry, these Damen vessels facilitate efficient and reliable operations, even in challenging waters.

The Platform Supply Vessel 3300 heralded a new era in the offshore industry for Damen when it delivered the 80.1 m World Diamond, the first of six PSV 3300 for Norwegian owner World Wide Supply. Jan van Os, Damen Product Director Offshore, says: “World Diamond opens a new chapter in our offshore strategy because it embodies the ‘Damen standard’ PSV for a market that is fast-changing.

Extensive range

“The starting point for all of the vessels in the new Offshore Series has been conceiving the right hull because this is vital in reducing fuel consumption,” says Mark Couwenberg, Damen Design and Proposal Engineer Offshore & Transport. “Hull shape, coatings, the location of oil tanks, refrigerants, recovery of waste heat and engine emissions – all of these are part of the E3 concept: to be environmentally friendly, efficient in operation and economically viable.”

Mark Couwenberg explains. “We spent considerable time on computational fluid (CFD) studies to investigate and simulate ship behaviour and optimise the hull shape. A model of the resulting hull has been tested at Maritime Research Institute Netherlands (MARIN) to verify the results. The slender hull reduces fuel oil consumption, not only in calm water but especially in rough seas. Smooth surfaces and a distinct lack of angles, lines and recesses also have a positive effect on the durability of coatings.”

Platform Supply Vessels:
Highly efficient, large-capacity ships, especially suited for transport of crew and supplies to and from offshore structures. The vessels may be optionally fitted with: Fire Fighting, Oil Recovery and/or high class Dynamic Positioning installations. The vessel design provides a safe and comfortable working environment.


Offshore Pontoons & Crane Barges:
Offers a full range of offshore, Heavy Lift and/or semi-submersible pontoons, from simple, but seagoing platforms to crane and pipelaying barges.


Construction Support Vessel:
Offshore oil, gas and wind fields need specialised vessels to install and maintain subsea equipment. The Damen CSV 8019 is designed with a large clear deck, a large accommodation area and can be fitted with ROVs, a 100ton subsea crane, moonpool, heli-deck, etc. A larger vessel of this type is under development. The CSV 8019 complies with Petrobras’ requirements for ROV Support Vessels.


Well Stimulation Vessel:
Increasing the production performance of deteriorated oil wells is often performed by old PSVs which have been retrofitted with the required pumping and mixing equipment. Damen has designed a versatile well-stimulation vessel in recognition of the fact that purpose-built vessels are increasingly coming to be seen as safer and more economical.


Anchor Handling Tug & Supply Vessels:
Part of the Anchor Handling Tug and Supply vessel category, offered from 70t bollard pull upwards, the 200t bp AHTS200 has been designed for water depths up to 3,000m.
The vessel features a 670m2 working deck, extensive winch lay-out, ROV functionality and can be used for subsea construction. The Damen AHTS 200 design was based on the Petrobras AHTS 18,000 requirements.


Fast Crew Suppliers:
More than 70 vessels featuring the unique Damen Sea Axe vessels bow ranging from 19m-67m have been supplied. These vessels cut through waves maintaining speeds of up to 20 knots, reducing slamming and vertical acceleration by up to 75%. The latest variant, a Twin Axe Bow version, the FCS 2610, is making an impact in the windfarm construction sector, handling crew transfer in wave heights of up to 2.5m and operating at speeds up to 25kn.


Fast Inspection Repair & Maintenance Vessel:
The FIRM concept vessel offers a substantial higher speed than existing designs. The concept features the successful Damen Axe Bow designs. The vessel offers the possibility to fit a motion compensated heli deck.


Damen Offshore Carrier:
A 7,500 – 10,000 dwt range multi-purpose vessel with heavylift, ro-ro and offshore installation capabilities. It features 65 days endurance, 2,300m2 of deck area, and deck strength of 20t/m2. The vessel can be fitted with the Damen Deep Dredge system, for mining and dredging.


Multi Purpose Vessels:
Designed to execute a great extent of specific tasks which may include coast guard duties, fishery control, fire fighting, rescue, oil recovery, salvage, wind farm maintenance. The vessel design-platform may be customised to suit specific client requirements.


Offshore Heavy Lift Vessel 1800:
A DP2 ship with two 900 tonnes mast cranes, 3,100m2 of free deck space and 20,000m2 of adjustable cargo hold. It can work in water depths of up to 3,000m.


Oil Spill Response Vessel:
An increasing demand for vessels which are able to respond to environmental disasters is expected, especially after the Macondo disaster. Having built a number of dedicated Oil Spill Response Vessels, Damen is working on a new type for this market. Like the CSV and the AHTS, this vessel is fit for the Brazilian market and incorporates Petrobras’ OSRV-requirements.
