THE GUARDIAN FLEET
The Guardian Fleet and individual vessel details are listed below.
MV OFFSHORE GUARDIAN
The MV Offshore Guardian is a 34m Catamaran designed, built and owned in Australia/NZ. She has been working in the offshore survey industry since she was built in 2015, working for CSIRO, HESS, PTTEP, Exxon, Neptune and Fugro. With 140m² of back deck space she is an ideal platform for coastal hydrographic survey operations. The vessel has a central moon pool for rigid, safe and easy deployment of the multibeam, single beam, SVP sensors or a USBL. The deployment system is designed to operate at a speed of up to 10 knots.
The vessel has a transit speed of 15 knots, permitting the vessel to access the most remote coastal locations as required by the clients. She has ample accommodation for a geophysical or a hydrographic survey team, who will typically remain onsite for a 30-day duration prior to crew change. When operating at survey speed of 4 knots, the MV Offshore Guardian consumes as little as 750 litres per day, making her environmentally-friendly. Her track record undertaking surveys for industry has demonstrated she is acoustically very quiet.
MV OFFSHORE EXPRESS
The MV Offshore Express is a 24m wave-piercing Catamaran designed, built and owned in Australia/NZ. She has been working in the survey industry since she was built in 2016. With 91m² of back deck space she is a more compact than the MV Offshore Guardian, and well-suited for coastal survey operations and can work to as little as 5m of water depth.
The vessel has a central moon pool for rigid, safe and easy deployment of the multibeam, single beam, SVP sensors or a USBL. The deployment system is designed to operate at a speed of up to 10 knots.
The MV Offshore Express back deck is illustrated, with inshore launch and Moonpool Deployment Pole and Tower in foreground. The vessel has a transit speed of 26 knots, permitting the vessel to rapidly access the most remote coastal locations.
She has ample accommodation for a hydrographic survey team, who will typically remain onsite for a 30-day duration prior to crew change. When operating at survey speed of 4 knots, the MV Offshore Express consumes as little as 750 litres per day, making her environmentally-friendly.
MV GURU
The MV Guru is a 24m Catamaran designed, built and owned in Australia/NZ. She has been working in the hydrographic survey industry since she was built in 2015. With 120m² of back deck space she is a compact version of the MV Offshore Guardian, and well-suited for coastal and protected water operations and will safely work to 5m water depth.
The vessel has a central moon pool for rigid, safe and easy deployment of the multibeam, single beam, SVP sensors or USBL. The deployment system is designed to operate at a speed of up to 10 knots.
The vessel has a transit speed of 15 knots, permitting the vessel to rapidly access the most remote coastal locations. She has ample accommodation for a hydrographic survey team, who will typically remain onsite for a 30-day duration prior to crew change. When operating at survey speed of 4 knots, the MV Guru consumes as little as 750 litres per day, making her environmentally-friendly. The MV Guru has a valid OVID, which is an offshore vessel inspection database used to screen vessels for offshore operations to ensure a vessel is of good standing.
MV OFFSHORE SOLUTION
Guardians’ new Multi-Purpose Support Vessel Offshore Solution is perfectly suited for operations in open and protected waters. With a length of 55 metres, a draft of minimum 2.80 metres and maximum 3.50 metres, and a cruising speed of 12 knots, she is diesel-electric powered by a combination of six Volvo Penta D13 diesel engines delivering 475 kW each; two 650 kW electric Omega Verhaar azipods providing aft thrust, and two 450 kW electric thrusters at the bow. The vessel is equipped with a DP2 system for dynamic positioning with an impressive DP-capability plot. At her stern is a six-metre-wide roller, with the option to install a 50-ton tugger winch.
Two Ø1.20 m moon pools can be used to deploy MBES, SBES, SVP and SBP sensors or USBL’s. A 20-tonne A-frame and davits will be used to deploy ROV’s, geotechnical, environmental and oceanographic equipment.
She can accommodate a sizable crew, with sleeping arrangements for 42 people and capacity for additional client offices on the vessel’s upper deck. Extra measures have been taken to avoid noise and vibration in the accommodation areas, and all cabins are equipped with TV, internet and air-conditioning. She has a duration of up to 40 days in the field.
UNMANNED SURFACE VESSELS

Guardian is acutely aware of the fourth paradigm shift appearing on our hydrographic horizon. Unmanned Surface Vessels (USV) promise the opportunity of providing vast quantities of data with a low HSE risk at a potentially lower price point than traditional surveys. At the very least, they should act as a force multiplier to conventional survey operations. USV are an ideal complement to our existing fleet for on-shelf operations. They can be deployed and recovered to the back deck and operated in parallel from our mothership.
Guardian will operate these vehicles in a supervised mode, slowly migrating to a fully autonomous mode when legislation and State legislation fully accommodates this emerging technology.
