Later developments allow for the berthing energy to be absorbed through the linkspan at the hinge but this will not protect from overriding of the ship or uplift from the bulbous bow.

As the wave counter effects are only significant at the vessel's higher range of speed, bulbous bows are not energy efficient when the vessel cruises outside of these ranges, specifically at lower speeds.

Marcantonio, 35, said the Starbound had been struck by a large, dark vessel with a bulbous bow, between several hundred and 1, 000 feet long, with blue bottom paint and some green markings.

Among the changes are a bulbous bow for improved flight operations, larger gear to land heavier aircraft, a relocated weapons elevator to improve safety and weapons movement, and more berthing spaces and facilities for women.

Tank staff also carried out research and experiments for other companies : Belfast-based Harland & Wolff decided to fit a bulbous bow on the liner " Canberra " after successful model tests in the Denny Tank.

Among the changes are a bulbous bow for improved flight operations, larger gear to land heavier aircraft, a relocated weapons elevator to improve safety and weapons movement, and more berthing spaces and facilities for female crew members.

Before entering service for Royal Cruise Line, she received a four-month refit at the Greek shipyards of Perama and Neorion, where her funnel was rebuilt, her topmost deck expanded and a bulbous bow added below the waterline.
38.
Experimentation and refinement slowly improved the geometry of bulbous bows, but they were not widely exploited until computer modelling techniques enabled researchers at the University of British Columbia to increase their performance to a practical level in the 1980s.
39.
The conversion consisted of retrofitting a bulbous bow, faired to the existing icebreaker bow, to reduce the wave resistance and replacing the ice-strengthened propeller blades with more efficient highly skewed blades, designed by KaMeWa, to improve speed and fuel consumption.

A good icebreaking bow, designed to break the ice by bending it under the ship's weight, has very poor open water characteristics and is subjected to slamming in heavy weather while a hydrodynamically efficient bulbous bow greatly increases the ice resistance.
