Journal of Marine Science and Engineering, 2023 Submarines with pumpjet propulsors have recently been used in many countries to improve their propulsion and noise performance. The pumpjet has the advantage of improving noise and cavitation performance by increasing the pressure inside the duct, and it

Computational Investigation of Seakeeping Performance of a Surfaced Submarine in Regular Waves
한국해양공학회지, 2022 A submarine is optimized to operate below the water surface because it spends most of its time in a submerged condition. However, the performance in free surface conditions is also important because it is unavoidable for port departure and arrival ...

Technical–Economic Feasibility Analysis of Subsea Shuttle Tanker
Journal of Marine Science and Engineering, 2021 This paper presents the technical and economic feasibility analysis of the subsea shuttle tanker (SST). The SST is proposed as an alternative to subsea pipelines and surface tankers with the primary purpose of transporting CO2 autonomously underwater ...

Solution of Supplee's submarine paradox through special and general relativity
, 2016 In 1989 Supplee described an apparent relativistic paradox on which a submarine seems to sink to observers at rest within the ocean, but it rather seems to float in the submarine proper frame. In this letter, we show that the paradox arises from a misuse

Meltwater Intrusions Reveal Mechanisms for Rapid Submarine Melt at a Tidewater Glacier [PDF]
, 2019 Submarine melting has been implicated as a driver of glacier retreat and sea level rise, but to date melting has been difficult to observe and quantify. As a result, melt rates have been estimated from parameterizations that are largely unconstrained by ...

Onshore Thermokarst Primes Subsea Permafrost Degradation
Geophysical Research Letters, 2021 The response of permafrost to marine submergence can vary between ice‐rich late Pleistocene deposits and the thermokarst basins that thawed out during the Holocene. We hypothesize that inundated Alases offshore thaw faster than submerged Yedoma.

Evaluating Ice Load during Submarine Surfacing and Ice Breaking
Journal of Marine Science and Engineering, 2023 At present, the calculation method of ice load on surface navigation ships has been very mature, but the calculation method of submarine ice load is very few. The reasonable evaluation of submarine ice load has become an urgent problem to be solved.

Research on the Combination of Underwater Acoustic Countermeasure Equipments Against Torpedo
MATEC Web of Conferences, 2016 Today the use of acoustic countermeasure equipment has become the main means in submarine defense torpedo operation. Combination of acoustic countermeasure equipments are used during the operation so that we can amplify the countermeasure effect.
