A Comprehensive Guide to Terrestrial Sphere Geometry and Parallel Sailing

 

QUICK ANSWER: TYPES OF SAILINGS IN NAVIGATION

Parallel Sailing:
• Vessel maintains constant latitude (090°T or 270°T)
• Used to calculate departure from difference in longitude
• Formula: departure = d.long × cos Latitude
• Historical method preferred by sailing ships in the 19th century
• Requires no external forces acting on the vessel

Position Reference Fundamentals:
► Latitude measured 0° to 90° North or South from equator
► Longitude measured 0° to 180° East or West from Prime meridian
► Difference in latitude (d .lat) named toward direction of movement
► Difference in longitude (d.long) always shorter arc or smaller angle
► If d.long exceeds 180°, subtract from 360° and reverse the name

Direction Reference Systems:
• Quadrantal notation: 0° to 90° from North/South to East/West
• Three-figure notation: 000° to 360° clockwise from North
• True course: angle between True Meridian

West P&I Club informs on the safe loading of Group A bulk cargoes under the IMSBC Code during wet weather, highlighting key procedures and moisture management requirements to ensure the cargo’s Transportable Moisture Limit (TML) is never exceeded.

As explained, the Club has recently seen several instances regarding loading bulk cargoes that are categorized as Group A cargoes under the IMSBC Code during wet weather. Group A cargoes should never be loaded where it has been determined that the moisture content of the cargo exceeds the Transportable Moisture Limit.

A Guide to Parametric Roll, Broaching, and Stability Loss in Waves

 

QUICK ANSWER: STABILITY WHILE UNDERWAY

A vessel's stability changes dramatically when moving through waves compared to calm water conditions. The metacentric height (GM) that you calculated at departure can increase or decrease by significant margins depending on where the wave crest sits relative to the ship's length. When a wave crest is at midships with troughs at both ends, your GM decreases—potentially to zero or negative values if the initial GM was small. This can trigger sudden capsize without warning, especially in following or stern quartering seas.

Key Points to Remember
► Six independent motions: Your ship moves in surge, sway, heave (translations) plus roll, pitch, yaw (rotations).

Essential standing orders for engine room operations and safety management

 

QUICK ANSWER

What are Chief Engineer standing orders?
► Written instructions issued by the Chief Engineer for engine room operations
► Ship-specific requirements reflecting vessel characteristics and trade patterns
► Complement company procedures while adding vessel-specific details
► Must be read, signed and dated by all engineer officers upon joining
► Kept readily available in the engine control room for reference
► Cannot conflict with SMS but provide specific operational guidance
► Reflect Chief Engineer's requirements and Master's standing orders
► Account for engineering team experience and vessel operational circumstances

What are standing orders for?
• Establish clear operational procedures for engine room personnel
• Define circumstances requiring Chief Engineer notification
• Specify machinery monitoring parameters and acceptable limits
• Outline daily routine checks and inspection requirements
• Detail watch handover procedures and responsibilities
• Provide safety protocols for hot work and hazardous operations
• Clarify environmental compliance procedures

Protocolo del puente, desencadenantes del STCW y puntos de decisión de la guardia de oficiales

RESPUESTA RÁPIDA: POR QUÉ Y CUÁNDO LLAMAR AL MASTER

El  Oficial de Guardia (OOW)  representa al Capitán durante los períodos de guardia asignados. Si bien tiene autoridad operativa para navegar con seguridad, existen situaciones específicas en las que  se debe llamar al Capitán de inmediato . Esto no es opcional, sino un requisito legal respaldado por el derecho marítimo internacional.

Por qué es necesario llamar al capitán
►  Autoridad suprema:  el capitán tiene la máxima responsabilidad legal del buque, la tripulación, la carga y el medio ambiente
►  Experiencia y conocimientos:  los capitanes aportan años de criterio a situaciones complejas que van más allá de la guardia de rutina
►  Mandato reglamentario: los códigos STCW,
