OSC’s Charter Vessel Specifications: MV Orca
OSC’s MV Orca is a general purpose survey vessel and workboat adapted for various uses, including marine mammal and bird surveys, crew transfers, safety, diving, wildlife watching, and fishing.
- Category 3 (20 miles from a safe haven, day or night)
- Seven persons (6+ skipper)
- Length: 7.72 m
- Breadth: 2.54 m
- Draught: 0.56 m
- Cruise speed: 10–15 knots
MV Orca is stored in OSC’s warehouse, situated in the coastal town of Dunbar. The vessel is transported, launched and recovered, using a heavy duty, double-axle, braked trailer, which includes a spare wheel and salt water flushing kit. A dedicated Toyota Amazon Land Cruiser 4.2L 4×4 is supplied for towing to locations throughout Europe. MV Orca is available to mobilise anywhere in Europe at short notice.
All safety equipment exceeds minimum requirements of the Maritime and Coastguard Agency (MCA).
Marine Mammal survey:
MV Orca is equipped with a detachable observation tower designed specifically for Marine Mammal & Seabird Observation (MMSO), which permits a minimum eye height of 5 m above sea level.
A stern-mounted davit/boom and detachable manual winch has been installed for the deployment and recovery of up to 500 m of Passive Acoustic Monitoring (PAM) hydrophone array cable or other oceanographic instruments. The on-board 2 KW Honda ‘whisper’ diesel generator can be used for powering environmental monitoring equipment exclusively. It has low-operational noise of just 52 dB (less than common speech), and three-pin electrical sockets inside the cabin with sufficient power to run several laptops and associated electronics. There is seating and table-ledges available for operators.

Third-Party Charter Vessels
OSC periodically hire charter vessels for survey work. Charter operators and companies are invited to submit their details, where vessels meet the desired specifications to support any of our range of services for both coastal and offshore projects.
Survey vessels should be seaworthy for the anticipated conditions and, if necessary, provide an observation platform of sufficient height and/or winches. When planning to tow hydrophone arrays from a charter vessel, a one-day acoustic trial period may be required to determine the relative noise regime. An acoustic trial may be spent traversing transects whilst testing and optimising the sensitivity of hydrophone arrays, prior to the main survey.
If you feel your vessel may be of use to OSC, please contact us.
OSC personnel are qualified to operate fast crafts and small vessels, for which they have received WIldlife SafE (WiSe) training and accreditation (‘Accredited Marine Industry Operator’), a scheme designed to promote universal protocol for safe navigation of boats in the vicinity of macro marine wildlife (e.g. cetaceans, pinnipeds, sharks and turtles) and minimise any disturbance to these animals. WiSe is a self-regulatory scheme that is entirely funded by the UK government and receives the logistical support of many mainstream international NGOs. For more information visit: www.wisescheme.org.
