The oceanographer's companion : essential nautical skills by George Maul

By George Maul

Scientists and engineers embarking on their first voyage for oceanographic or meteorological examine are frequently unprepared for the adventure. Going to sea consists of studying a brand new language – that of the seaman. this is often worthy for transparent communications, for the security and wellbeing and fitness of the contributors of the medical celebration and the ship’s team. The Oceanographer’s spouse is meant to familiarize a scholar with the fundamentals of navigation, seamanship, marine engineering, communications, safety-of-life-at-sea, shiphandling, knots and splices, first relief, and much more. The ebook could have a truly sensible believe with plenty of examples.

Sample text

Starboard seems to have originated from the use of a steering oar near the stern on the righthand side of a ship, the steer-board side; steering oars were known in Egypt five millennia ago. The opposite side, today’s port side, probably is Middle English in origin derived from the term larboard, or loading side of a ship; it became the side facing the harbor (the port) in fifteenth century usage. 1 is a view from the starboard side of a proposed research vessel. The vessel particulars are molded length = 78 feet, waterline length = 73 feet, molded beam = 24 feet, and full load draft = 6 feet.

Gross tonnage is arbitrarily chosen to be the volume in cubic feet divided by 100. 67 L × b × D/100 9/10 gross tonnage Both gross tonnage and net tonnage are space tonnage not displacement tonnage. Research vessels are not cargo ships, so although they may be given values for net and gross tonnage for taxation or canal transit cost calculations, these are not used in calculating stability. Trim on a ship is a measure of longitudinal stability. At the forward perpendicular near the stem (the vertical line where the water line intersects the hull at the bow), and at the aft perpendicular near the stern (an imaginary vertical line through the rudder post), are permanent markings indicating how much Stability and Trim 31 draft there is.

The basic s­ tructure discussed in Chapter 4 will remain: bulkheads, watertight doors, sea chests, heads, hull, weather deck, pilothouse, overhead, and so forth. 3) may have a bow observation chamber, a weather-balloon shack, a gravity lab, or an acoustic instruments lab, all of which will be under the supervision of survey technicians and the chief scientist. A few examples follow. Aft of the bridge on a large ship, especially a hydrographic survey ship, will be the plotting room. This space is the center for gathering bathymetric data.
