Octopuses are fascinating creatures with a unique physiology and exceptional intelligence. They are cephalopods, part of a spineless class of marine animals that also includes squids and cuttlefish. With their eight limbs, ability to change skin colour, and complex nervous system, octopuses have captured the human imagination for centuries, appearing in art, literature, and mythology. They are also the subject of extensive scientific research, with their intelligence and biological differences from humans making them ideal candidates for understanding complex brain function and inspiring medical and technological breakthroughs.
Research vessels are boats or ships designed for scientific exploration at sea. These vessels can be constructed with icebreaker hulls, enabling them to navigate polar waters and operate in diverse environments. One such vessel is the megayacht Octopus, owned by Microsoft co-founder Paul Allen. This 126-metre yacht has been used for various rescue and research missions, including the study of a living fossil, the coelacanth, once believed to be extinct.
In this article, we will delve into the captivating world of octopuses, exploring their biology, behaviour, and the boats that enable us to study them in their natural habitat. We will also discuss the importance of marine research vessels and their role in advancing our understanding of the ocean and its inhabitants.

What You'll Learn
Oceanographic research vessels
The design of an oceanographic research vessel depends on its intended role. Some vessels require excellent sea-keeping capabilities, while others need to be highly manoeuvrable or have low noise characteristics. In some cases, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters and navigate through ice.
The Scripps Institution of Oceanography operates several research vessels, including the R/V Robert Gordon Sproul, a regional general-purpose research vessel serving research and education missions off the coast of California and the US West Coast. Another example is the R/V Bob and Betty Beyster, a purpose-built coastal research vessel designed for efficient operations off the Southern California coast and throughout the Channel Islands.
The Floating Instrument Platform (FLIP), operated by the Scripps Institution of Oceanography, is a unique oceanographic research tool. It is a 355-foot vessel that can be rotated 90 degrees so that 300 feet of its length extends vertically out of the water, providing a stable platform for conducting a variety of scientific experiments.
Vard Marine is a company that specialises in designing research vessels. They have designed more than 30 vessels for funded programs spanning different types of research, including hydrographic, seismic, fisheries, meteorological, and oceanographic exploration. Their designs take into account the specific requirements of each project, ensuring that the vessel is perfectly suited for its intended research and operating conditions.

Hydrographic survey vessels
In addition to their hydrographic capabilities, these vessels often perform multiple roles. They may function as oceanographic research ships, studying the physical, chemical, and biological characteristics of water and the atmosphere. They can also be used for naval research, such as submarine detection, or for oil exploration, using seismic sources like air guns to detect potential deposits beneath the seabed.

Fisheries research vessels
- Quiet platforms: To avoid disturbing fish and other marine life during data collection.
- Ice-strengthened hulls: For research in polar or icy regions, the vessel may need to navigate through ice-covered waters.
- Strengthened A-frames and hangar spaces: If the vessel will be used for deploying and recovering submersibles or underwater vehicles.
- Large reinforced deck spaces: To accommodate equipment such as streamer reels, air guns, and rigging for handling air gun arrays.
- Efficient propulsion and fuel consumption: As fisheries research vessels may need to cover large areas and operate for extended periods, efficient fuel usage is essential.
- Winches and handling equipment: For deploying and recovering research equipment, such as conductivity-temperature-depth (CTD) devices, coring devices, and trawls.
- Dynamic positioning: The ability to maintain position in strong winds, currents, and high sea states is crucial for safe and stable operations.
- Laboratory and storage space: Adequate laboratory areas are needed for data analysis, sample storage, and scientific equipment.
- Single berthing and natural light: These features promote healthy sleep patterns and well-being for the crew and scientists on board.
- Compliance with regulations: Fisheries research vessels should adhere to environmental regulations, such as the International Maritime Organization's (IMO) MARPOL regulations, to minimise their impact on the marine environment.
Overall, the design of fisheries research vessels must balance the specific needs of fisheries research with cost considerations and adhere to industry requirements and advancements.

Naval research vessels
Naval hydrographic survey vessels often do naval research, such as on submarine detection. They are designed to conduct hydrographic research and surveys, producing nautical charts to ensure safe navigation by military and civilian shipping. They also conduct seismic surveys of the seabed and the underlying geology, useful for detecting geological features likely to bear oil or gas. An example of a hydrographic survey vessel is CCGS Frederick G. Creed.
The design of modern naval research vessels can be traced back to the early voyages of exploration, with James Cook's Endeavour being a notable example. The Endeavour was a sturdy vessel, well-equipped for the challenges of exploration, and fitted with facilities for research personnel.

Polar research vessels
One example of a polar research vessel is the RRS Sir David Attenborough, which is one of the most advanced polar research vessels in the world. It has a range of 19,000 nautical miles at a cruising speed of 13 knots and can spend up to 60 days at sea. The ship is designed to support science in extreme environments, with a wide range of specialist scientific facilities, instruments, and laboratories. It can deploy, operate, and control a range of remotely piloted science instruments, including marine robotics and remotely operated vehicles, to capture data from the deep ocean and previously inaccessible locations under the ice.
Another example is the RV Polarstern, a well-known polar research vessel that conducts research in both the Arctic and Antarctic regions. Polar research vessels, like the USCGC Polar Star, RSV Aurora Australis, and RSV Nuyina, are often constructed around an icebreaker hull, allowing them to engage in ice navigation and operate in polar waters. They usually have dual roles, particularly in the Antarctic, where they also function as polar replenishment and supply vessels to the research bases.
