Chartering-Commencement of Laytime

...Commencement of laytime Determining when laytime commences is essential for both owners and charterers. Both need to be aware when laytime starts so that any demurrage claim can be accurately evaluated. It is therefore important that both owners and charterers are able to effectively analyse the terms of the charterparty which deal with the conditions which need to be satisfied before the laytime clock starts running. I will review the main conditions that are generally required to be satisfied and indicate some of the common pitfalls and errors which can arise. In general there are three main conditions which need to be met under most charterparties before laytime can commence. These concern the arrival and readiness of the vessel and the tender of the Notice of Readiness ("NOR"). We will consider these in turn. Arrival The first requirement for the commencement of laytime is that the vessel must be arrived ship. Simply, to have 'arrived' at a port, a vessel must have reached either the loading/discharging place or, should that place be busy, the normal waiting place. The vessel must be “arrived ship” so that the notice of readiness will be valid when given. If the Notice of Readiness is invalid when given, it will be ineffective to trigger the laytime (or to start the "laytime clock") upon the expiry of the stipulated period of notice. Notice of Readiness can be given orally, but usually a written form is used. It is an important function of a port agent to......

Transportation

...Impact of unstable Economic on Transportation Like many economic activities that are intensive in infrastructures, the transport sector is an important component of the economy impacting on development and the welfare of populations. When transport systems are efficient, they provide economic and social opportunities and benefits that result in positive multipliers effects such as better accessibility to markets, employment and additional investments. When transport systems are deficient in terms of capacity or reliability, and the unstable economy hey can have an economic cost such as reduced or missed opportunities. Transport also carries an important social and environmental load, which cannot be neglected. Thus, from a general standpoint the unstable economic impacts on transportation can be direct and indirect: • Direct impacts related to accessibility change where the unstable economy is disabling larger markets to save time and costs. • Indirect impacts related to the economic multiplier effects where the price of commodities, goods or services drop and/or their variety increases. Mobility is one of the most fundamental and important characteristics of economic activity as it satisfies the basic need of going from one location to the other, a need shared by passengers, freight and information. All economies and regions do not share the same level of mobility as most are in a different stage in their mobility transition. Economies that possess greater mobility are......

Factors to be considered when planning for building a road : The highway roads and those which are designed for heavy lift trucks should pass out towns and cities in order to minimize traffic, noise and pollution inside the towns.

Dvd for Less Case Study

...DVD For Less DVD for less is an online business that makes all of its money from customers that shop for DVD players online. Their competitive advantage is that they can sell DVD players for around $200 less than its competitors because it benefits hugely from low costs from its suppliers. DVD for less has now outsourced its warehousing and storage activities to an external firm, this firm is called Baselio Logistics who is charging them $500,000 annually for the warehousing of their inventory. This strategic move is going to have a positive impact on the business overall because their costs will decrease drastically. These costs that will decrease include the warehousing costs, average inventory costs and the carrying costs. Previously DVD for less was paying $1.46 million for warehousing and had an average inventory of $5 million of which the carrying cost was $1.25 million. Also under these circumstances their order fill rate was 97% and of the other 3% of the customers, 1% would cancel their orders and 2% would be unhappy but wait for the second delivery all these customers would also be compensated for the company’s mistake with a $35 coupon towards any of their products. Every late order would also have a handling fee of $20 per order so this would be a waste of $55 per customer for every customer that received the incorrect order. This is another extra cost that the company would need to pay. After the company’s warehousing and storage was handled by Baselio......

Globalization

...Week 1 – Assignment 1: Globalization Describe FIVE ways in which globalization of processes increases competitiveness of firms in your country. Globalization is the most important factor in a company’s growth and continued success within today’s competitive market. Competition in both domestic and foreign markets is increasing steadily, making it mandatory for companies to keep a global focus and strategy to maintain or grow their current market share. Domestic firms have managed to increase their competitiveness through globalization of processes. For example, some domestic companies have managed to outsource many of their engineering and technological development to other countries which decreases overhead expense. This type of function allows the company to drive out cost and become more attractive in its domestic environment. Companies have also looked at the purchasing process and have opted to purchase their supplies from differing global suppliers. These globally sourced products are relatively cheaper than domestic products, which again drives cost out and helps maintain a company’s competitive advantage. Domestic firms have also streamlined the communication process as a means of improving the global communication process through internet, instant messenger, cell-phones, etc. Companies that have lowered transportation costs in a global environment will have a great competitive advantage over other organizations whose process is not as streamlined.

Sourcing Style

...TYPE OF SUPPLY BASE When choosing what type of supply base to source from HL for COS must first decide whether they want to source from a narrow or wide supply base. Both have advantages and disadvantages, for example a wide supply base offers choice and flexibility as well as variety but a narrow supply base creates greater negotiating power as you build up a closer relationship with the supplier. As HL for COS is a carefully selected range of just 32 pieces a narrow supply base is more appropriate in this case as it offers the chance to have a greater involvement and control over the production of the garments. This would be a necessity when creating the HL for COS range. SOURCING STYLE The H&M group use Hubs when sourcing their garments this means that they have smaller offices regulating and controlling the factories they use during production of garments this helps with communication between the supplier and the company as well as regulating and monitoring the working conditions of the people employed by the supplier and ensuring that garment production runs smoothly. The choice of using a hub is one of many, including working directly with the supplier, sourcing from a wholesaler and using an agent to source product.
