Patent number: 4960347Abstract: This invention teaches that when a section of a tanker is damaged, the ship being far from shore-based help, it is imperative that the liquid cargo be transferred from the ruptured tank to an undamaged tank on the ship as quickly as possible. By doing so, the contents of the damaged tank are less likely to escape in a sufficiently voluminous quantity to seriously befoul the environment. To that end, a normally-empty emergency holding tank is provided on the ship with means to provide for emergency transfer of the liquid cargo from the damaged section into the emergency holding tank. At the same time, the ruptured tank is enshrouded by a flexible barrier curtain to entrap whatever liquid cargo that may have leaked from the damaged tank.Type: GrantFiled: February 13, 1990Date of Patent: October 2, 1990Inventor: Booth B. Strange

Patent number: 4881847Abstract: An arrangement to increase (or decrease) the temperature in sea or lake water within a limited area.The arrangement is constituted by a basin (F, P1-P4, V1-V3, N1-N3 etc.) which is constructed and located in the sea water which temperature is desired increased. The basin shall primarily make the water circulation difficult between the basin and the outer sea so that a temperature difference is achieved, but it is not fully tight to allow a certain circulation. In one model (FIG. 1) the water circulation is uncontrolled with firm and statically arranged elements (YP1-YP3, HP1-HP7, E1-E10). In another model (FIG. 5) the elements of the basin (J1-E10). In another model (FIG. 5) the elements of the basin (J1-J3) are operated with regard to a temperature aimed at. Several more models (FIG. 8, FIG. 9, FIG. 12 etc.) are described.Type: GrantFiled: December 1, 1986Date of Patent: November 21, 1989Inventor: Claes M. C. Sandels
