Key Features:

The Curtis Marshall is a 26m Dive Support Vessel (DSV) which offers a number of features unusual for vessels of this size. An on-board decompression chamber, integrated dive control, ballast transfer capability and a four point mooring system provide a safe and reliable working platform.

With a duration of up to 21 days for up to 12 charterer personnel, this flexible vessel has also been proven on complex geophysical campaigns. Acquiring multibeam bathymetry, side scan sonar, magnetometer and sub-bottom profiler data, the Curtis Marshall benefits from a spacious working deck space, 3 survey pole mounts, a 5T A-Frame with 3.5T integrated winch and 2 x 8m boom arms.

The spacious wheelhouse provides a 360 degree view, with the large area aft of the wheelhouse available for survey equipment installation and 3 dedicated workstations for charterer personnel.  

  • Control of 4 point mooring system while monitoring winches.
  • Walkabout Control can be docked next to helm or in front of CCTV screen.
  • Clear-Com intercom link to dive control, mess room and deck.
  • CCTV dome camera for all round vessel monitoring.

Unique Bow Fender Assembly

Designed specifically for the offshore wind market, the vessel is equipped with a bespoke design bow fender for engaging with the wind turbine fender, supporting both tower access for ropes teams and crew transfers between vessels.

Since launch, the vessel has been proven in safely accessing surf ladders, in conjunction with Dive Support operations.

Ballast Water Transfer System

With a fresh water capacity of circa 21,000 litres, water can be transferred between either of the two aft tanks and the forward tank.

5.5 Tonne Lift Capacity

The location of the HEILA crane on the port side of the main deck allows DSV Curtis Marshall to lift 5.5T over the side of the vessel.

Full Walkabout Vessel Control

Bespoke walkabout control system detachable from the helm position which can control all four mooring winches, steering, propulsion and bow thruster.

Exceptional Accommodation

Unlike many vessels of this size, DSV Curtis Marshall has been designed to comfortably accommodate 12 charterer personnel for up to 21 days.

The onboard accommodation includes:

  • 18 POB including 12 for charterers
  • 4 x double berths and 2 x triple berths below decks, each with sinks
  • 2 double berths above deck, including double skipper's berth with en-suite.
  • 4 x toilets and 4 x showers
  • Spacious Galley with seating for 8
  • Galley features a steam oven, hob, microwave, grill, 3 x fridges and 2 x freezers.
  • Mess room with TV and other facilities
  • Wheelhouse with 360-degree views
  • 21,000 litres of fresh water on board
  • Hot drink station accessible from deck
  • Storage area for work/wet gear
  • Laundry facilities

ROV Support

The Curtis Marshall offers a stable and versatile platform for ROV survey and inspection campaigns.

With the generous deck space available ROV operations can be carried out on their own or in conjunction with the inbuilt Dive system. A 20ft container for an ROV can be fitted leaving enough space to access the deck all round.

Features include:

  • Capacity to accommodate ROV control centre on vessel bridge
  • A-Frame Launch
  • Crane Launch
  • Capacity for dedicated LARS at the stern
  • Accommodates light work class such as Saab Seaeye Cougar XT ROV.

Dive Support

The DSV Curtis Marshall is a highly capable Dive Support Vessel, offering many features unusual for vessels of this size.

Built to IMCA D023 standard, the three-diver system allows for rapid mobilisation. Supported and maintained by Sub Aqua Diving Services, the vessel has completed hundreds of successful air dives.

The vessel benefits from a high capacity deck area for diving containers, accommodation onboard for up to 12 charterer personnel, and high specification IT and communication equipment such as Diver CCTV, Clear-Com system, and UPS's for all dive equipment.

Hydrographic, Geophysical & UXO Survey

The vessel is extremely adaptable, and we pride ourselves on being able to provide bespoke in house engineering to enable the vessel to carry out any task required.

With our in-house fabrication facilities we can manufacture adapters for any piece of equipment at a moments notice. This capability along with options for towing sidescan sonars and magnetometers, makes the vessel a capable and flexible survey solution.

The vessel offers 3 survey pole options which can be used to mount USBL transceivers, sub bottom profilers and multibeam echosounders. For survey campaigns, our offline processing office replaces the diving equipment container to maximise onboard processing capability.

The vessel is also exceptionally fuel-efficient, and can use as little as 15-20 litres per hour at a survey speed of 5 knots.

Previous survey spreads include:

  • Multibeam Echosounder
  • Side Scan Sonar
  • Innomar Sub Bottom Profiler
  • Towed Magnetometer Array
  • Environmental Sampling Equipment
