A) 1.8m wide (3 work stations) internal helm desk with 24” 4K Touch screen with Intel NUC+ 1.2m (2 work stations) kitchen bar table (internal with AC);
B) 12 person dining table (8+ work stations) (external but full shaded).
Deck Area: 85 m2 of total free deck area comprising:
A) 50sqm (8m x 6.2m) catamaran main nacelle (half shaded) includes wet lab area & 12 person table dry lab area.
B) 11m2 (8m x 1.3m) of adjoining lower rear platform (fully shaded)
C) 24m2 (8m x 3m) of upper rear platform (unshaded).
In addition there is 60m2 of open trampolines space at front of vessel which can be partly shaded. Not suitable for heavy equipment.
AUV
Support for deploying and recovering AUVs up to 5.5m long & 700kg via dual rear winches & telescoping support beams (TBD 2027)
ROV
Support for deploying and recovering ROVs (up to 200kg & 2000m depth via fibre optic oceanographic winch (TBD 2027)
Submersible:
Support for deployment of small submersibles (up to 1000kg) via mast lift and trampoline moon pool.
Flight:
Support for multiple drones including large models.
A) The 24m2 (8m x 3m) upper rear platform provides excellent launch point for drones, including large models. It is unobstructed to the sides and rear and only has two ropes to the mast top that could be removed in the forward direction.
B) The 60m2 of front trampolines are also an excellent location for launching & recovering drones with the ability to cut engines and just drop on soft trampoline material.
