1. Accommodation engineering vessel.
Due to the increasing number of offshore oil and gas fields in the world, the engineering operations for stable and increased production of offshore oil and gas fields are constantly increasing, and the market demand for accommodation engineering ships will continue to increase year by year in the future. At the same time, due to the decreasing number of new construction in shallow water oil and gas fields in recent years, while the number of new construction in deep water oil and gas fields has been increasing year by year, and some shallow water oil and gas fields have reached their design life and will be abandoned, the demand for accommodation engineering ships in the future will mainly be semi submersible and DP ships. Not only will the vast majority of new accommodation engineering ships be semi submersible and DP ships, but there may also be a market trend of transforming old self elevating or anchored accommodation engineering ships into semi submersible or DP accommodation engineering ships.
2. Crane/pipe laying vessel.
In the future, there will be mainly two types of crane/pipe laying ships: crane/pipe laying ships and pipe laying ships. There is not much room for further expansion of the market demand for crane ships, so the number of newly built crane ships is likely to decrease year by year. The future demand for crane ships may diverge. On the one hand, crane ships are likely to fade out of the deepwater engineering field, and the installation of underwater production systems and floating production systems for deepwater development in the future will not require heavy lifting
Ships, and some lifting operations tasks can be undertaken by crane laying vessels, therefore the market demand for heavy-duty deepwater crane ships will increasingly decrease; There is a huge market demand for deepwater lifting operations below 500 tons, but this part of the work tasks will be largely carried out by multi-purpose ships replacing light deepwater lifting ships, so the total market demand for deepwater lifting ships will be very limited.
On the other hand, the application of crane ships in shallow water areas will shift from installation operations to a combination of installation and demolition operations. Previously, crane ships that were suitable for installation operations may not be very suitable for demolition operations. Therefore, the market demand for demolition operations in the future will trigger the emergence and widespread application of new concept crane ships.
Due to the fact that most deepwater lifting operations suitable for hoisting in the future are below 1000 tons, the lifting capacity of deepwater lifting and pipe laying vessels will remain at a moderate level, and there is a significant market demand for deepwater lifting and pipe laying vessels with a lifting capacity of around 1000 tons. The pipeline laying performance of crane and pipeline laying ships will be the focus of future market attention. Crane and pipeline laying ships that combine two or more pipeline laying functions are the target of market pursuit. In order to improve operational efficiency, crane and pipeline laying ships with stronger storage capacity, more welding stations, and larger effective deck area are more favored by the market; Due to the need to improve job safety and efficiency, the market demand for Reel lay pipe laying vessels will continue to increase in the future.
3. Underwater work vessel.
Due to the higher frequency of mobilization, underwater work vessels undoubtedly emphasize the importance of speed more than other types of engineering vessels. Continuously improving the speed of underwater work vessels will be a long-term and important research and development topic, and the maximum speed of the new generation of underwater work vessels in the future can reach around 20 knots.
Among the three types of ships, namely diving support ships, multi-purpose ships, and ROV support ships, ROV support ships and multi-purpose ships have broader market prospects. Due to the increasing number of deepwater oil and gas fields and the widespread application of underwater development models, the market demand for ROV support ships will continue to grow; Whether it is the development of underwater production systems or the use of floating production systems, multifunctional ships have a place to play, so the market demand potential for multifunctional ships is also very huge; However, the operating depth of diving support vessels is limited to 350 meters, and the growth of future market demand is weak. There may be a downward trend in the number of new constructions within the next decade.
With the further development and application of modular technology, the modularization of specialized operation equipment will make the functions of multifunctional ships more diversified, and at the same time make the conversion of various operation modes safer and more convenient. In the future, multifunctional ships will be able to achieve quick conversion of multiple operation modes when in place or during navigation at sea, greatly improving the utilization efficiency and economic benefits of ships.
4. Other engineering vessels.
Trench digging and pipe laying ships and well repair ships have great development prospects and may surpass crane ships to become important ship types in the future marine engineering market. Due to the frequent occurrence of accidents in offshore oil pipelines, the government and oil companies are paying more and more attention to the safety of underwater oil pipelines. To ensure safety, not only are shallow water pipelines required to be dug and buried, but also strict requirements for deep water pipelines have been put forward, and higher requirements have been put forward for the depth of digging. Owners have also imposed stricter quality inspections on construction units for digging and burying pipelines. It can be inferred that there will be a significant demand for trench digging and pipe laying ships in the future market.
At the same time, in order to reduce the cost of offshore oil and gas development and improve the safety of development, oil companies are constantly improving and innovating traditional development practices. Currently, many advanced oil companies are adopting new drilling and well repair technologies, shifting part of the well repair work traditionally undertaken by drilling platforms to be completed by engineering ships. It can be predicted that the amount of well repair operations carried out by engineering ships will increase in the future, and well repair ships have a very broad market development prospect.
