The partitioned tanks which surround the hold are used for ballast purposes. This hold shape also results in a self-trimming cargo. During unloading the bulk cargo falls into the space below the hatchway facilitating the use of grabs or other mechanical unloaders. Large hatchways are a particular feature of bulk carriers.

Nov 1, 2001 · The problem definition for the hatchway watertight integrity of bulk carriers starts with defining bulk carrier as any ship designed, constructed and/or used for the carriage of solid bulk cargo [11]. Herein ‘solid bulk cargo’, based on the definition given in SOLAS/Conf.4/25 Chapter XII Regulation Definitions, means any material, other ...

Hatchway elliptical corner-plates (gussets) at weather deck level. The diagram on the RHS shows the extended longitudinal hatch coamings. To provide additional strength, beams and longitudinal girders are arranged i.w.o. the hatch opening.

Nov 1, 2001 · All the procedures and inputs/outputs of FSA application to the hatchway watertight integrity of bulk carriers are presented. Based on the experience throughout this FSA application, it is thought that more detailed descriptions and stricter discussions are necessary on several aspects in the FSA process, namely Causal Chains, RID and RCOs.

The disadvantage of a ship’s hatchway lies in the fact that—in effect—it is a very large discontinuity as far as the ship’s deck is concerned. This reduces the strength of the deck so steps must be taken to reinforce the deck and overcome this negative effect.

Mar 1, 2022 · The AICA comprises the following 4 segments 1 (Figure 2): (1) anterior pontine segment (A1)—starting from the origin of the AICA, proximal to the CN VI root exit zone, and ending inferiorly along the long axis of the inferior olive; (2) lateral pontine segment (A2)—starting from the anterolateral margin of the pons through the cerebellopontine angle up to …

Jan 15, 2017 · The development of autonomous, energy efficient, underwater robots for large areas exploration has been attracting many researchers, since their use c…

Sep 24, 2004 · The mammary gland parenchyma arises from a single epithelial ectodermal bud. Most authors agree on the successive stages of development of the mammary gland during the embryonic and fetal stages, there are variations in nomenclature, and the exact time of appearance of each structure varies whether the authors choose to express the age of the embryo based on the estimated time of conception ...

Mar 1, 2024 · The main reasons for the low speed of the energy transition are the relatively low cost of fossil fuels in comparison with carbon-free fuels and the long investment cycle of power equipment (for instance, the investment cycle of the steam and gas turbine power plant is more than 20 years) [5], [6].
